and a ring 29 fitting tightly upon the shaft prevents oil from creeping out from the journal box along the shaft. The inner end of the journal box 25 has a slot 80 made therein to permit a ring oiler 31 to bear upon the shaft 24.

In use, the trough is partially filled with a liquid lubricant, and as the contained mechanism 22 is actuated the lubricant is churned by the moving parts which thereby become lubricated.- Owing to the splashing about of the liquid in the casing, the grooves 7 in the edges of the trough become filled with the lubricant to the extent that the lower edges ofthe beads 12 of the cover are submerged. Thus, the oil-charged atmosphere that is circulated by the moving meohanism is retained within the casing. Any overplus of oil that may enter the grooves, either overflows the internal lips 9 back into the trough, or flows into the chamber 6 and returns into the trough through the ducts 5. In this manner the contained lubricant that is splashed about within the casing instead of seeping out from between the trough and cover to the exterior of the casing, fills the traps be tween the edges of the trough and cover from which it overflows'back into the trough.

lVhat I claim'is:-

1. In a casing for actuating apparatus, a base including a trough adapted to hold a body of lubricating oil, and having at its upper edges interior and exterior lips with corresponding grooves intervening therehetween, the interior lips extending in a plane lower than the exterior lips; a cover supported over the trough and having pendent beads projecting respectively into the grooves, there being open space between the lips'and beads; and mechanism enclosed by the trough and cover adapted to agitate the oil and to be lubricated thereby, the said grooves, lips and interposed beads forming a trap adapted to prevent escape of oil out from between the trough and cover.

2. In apparatus for inclosin mechanism to be actuated and lubricated therein, a trough having a chambered saddle at each end thereof for supporting the mechanism, r

and a corresponding duct leading from each chamber into the trough, and having also grooves respectively in its upper edges that extend into the chambers; and a cover having a chambered cap at each end thereof adapted to rest upon the corresponding saddle and support the cover over the trough, and having also beads depending respectively from its lower edges into said grooves, there being open space between the sides of the grooves and beads forming a trap.

In apparatus for enclosing mechanism to be actuated and lubricated therein, a trough having a chambered saddle at each end thereof for supporting the mechanism, there being a duct leading from each chamber into the trough and having also a groove in each upper edge that extends across the upper faces of the saddles into the chambers; and a cover having a clnunbered cap at each end thereof adapted to fit upon the corresponding saddle and having along each of its lower edges a bead projecting into the corresponding groove in the trough and an exterior ledge having a groove in its under side that extends across the adjacent lower faces of the caps into the chambers thereof.

at. In a gear casing a trough, and a cover therefor, there being formed in the upper edge of the trough a groove with an overflow outlet into the trough, and on the cover a corresponding bead that is suspended in said groove, the adjacent surfaces of the, trough and cover being spaced apart.

In testimony whereof I allix my signature, in presence 01 two witnesses.
